Drag-and-drop Guide, Meaning , Facts, Information and Description
Drag-and-drop refers to the act of (or support for the act of) clicking on a virtual object and dragging it to, or onto, another virtual object. The basic sequence involved in drag-and-drop is:- press, and hold down, the button on the mouse or other pointing device, to "grab" the object,
- "drag" the object/cursor/pointing device to the desired location,
- "drop" the object by releasing the button.
- dragging a data file onto a program icon or special window for viewing or processing,
- moving or copying filess to a new location/directory/folder,
- adding objects to a list of objects to be processed,
- rearranging widgetss in a graphical user interface to customize their layout,
- dragging a command onto an object to which the command is to be applied,
- e.g. dragging a color onto a graphical object to change its color,
- dragging a tool to a canvas location to apply the tool at that location,
- creating a hyperlink from one location or word to another location or document.
Dragging requires more physical effort than moving the same pointing device without holding down any buttons. Because of this, a user cannot move as quickly and precisely while dragging (see Fitts' law). However, drag-and-drop operations have the advantage of thoughtfully chunking together two operands (the object to drag, and the drop location) into a single action (see, for example, Buxton, W. (1986). Chunking and Phrasing and the Design of Human-Computer Dialogues, Proceedings of the IFIP World Computer Congress, Dublin, Ireland, 475-480. http://www.billbuxton.com/chunking.html ).
